When it goes wrong · Char
Charred outside, raw inside, on something thick.
Can you save it?
Reviewed for this symptom
Move it to a lower heat or a moderate oven, covered, until the inside is cooked; the charred surface stays as it is. For a pepper or aubergine you will peel, this is correct and needs nothing.
How to confirm the diagnosis
Observable cues, not inferred user state
- A blackened skin over a raw, firm centre
- The piece is thick and meant to be eaten whole
- It was only ever over high direct heat
Not this?
- The whole dish tastes bitter and burnt.
- Vegetables went soft and grey without blackening.
- Acrid rather than smoky.
What actually happened
Only this symptom
Correct for a pepper you are going to peel, wrong for anything eaten whole. Match the technique to whether the interior needs cooking.
The full mechanism
Shared by every char failure
Char sits past browning. Maillard reactions and caramelisation give sweetness and depth; pyrolysis — the thermal breakdown of the food itself — gives smoke, bitterness and a set of compounds nothing else produces. Used as a whole-surface treatment that is a mistake, but used in patches against unburnt food it reads as smoke and complexity rather than as burning. That contrast is the entire technique: a fajita pepper blistered black in spots against green flesh, a tortilla with dark freckles, an aubergine burnt entirely on the outside so the flesh inside tastes of smoke. It works because the bitter compounds stay concentrated at the surface while the flavour they contribute disperses. Charring also demands a dry surface and real heat — food that is wet or on a moderate flame goes grey and steams long before it can blacken.
The full Char lesson — how to tell, where to practise it, what it carries to.

Prevent this specific failure
Char thin things, or char the outside and then finish thick pieces with gentle heat; match the technique to whether the middle must cook.
What right looks like
Shared by every char failure
- Black patches against unblackened surface — evenness is the failure, not the goal.
- The smell turns smoky and slightly sweet; sharp and acrid means it has gone past useful.
- Skins blister and lift away from the flesh underneath, which is what makes charred peppers peel.
- It happens fast. Anything taking several minutes to char is not hot enough and is drying out instead.
